I installed a website and apparently the external DNS all worked fined to access the site: http://example.com
The problem was that internally, when on their network, they couldn't access the site, which I wasn't sure why as they kept on getting the error: Could not resolve DNS server.
Eventually their network guy came back to me and told me that they solved it as apparently WordPress was stripping away the www from their URL.
My question is, does WordPress actually strip away the www?
If so, do I need to set the Site (URL) to actually be: http://www.example.com as apparently he tells me that this is not ideal practice?
I have installed alot of WordPress sites and in the Site (URL), I have never included the www at the beginning.
Would appreciate your help.
